The Thomas B. Fordham Institute, a conservative think tank that authorizes charters in Ohio, sponsored an evaluation of charters in that state by CREDO of Stanford. CREDO is led by Margaret (Macke) Raymond and has completed many charter evaluations. Critics gripe that CREDO is funded by the charter-loving Walton Family Foundation and that Raymond is the wife of conservative economist Eric Hanushek, but it has nonetheless gained a reputation for balance and nonpartisan judgment.

Stephen Dyer here reviews the findings of the latest CREDO study of Ohio charters. There are good charters and bad charters, but on the whole, the findings are negative for students in charters. Over 40% of charters are doing very poorly. The students in these schools fall farther behind every year.

“Overall, kids in charters lose 36 days of math and 14 days of reading to their traditional public school counterparts. Of the 68 statistically significant differences CREDO found between charters and public schools, 56 showed a negative charter school impact, and 12 showed a positive one.”

Dyer points out that the state spends more than $900 million a year for these disappointing results. This money is taken away from community public schools.
